RAILWAY-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 606,197, dated June 28,1898.

Application ned January is, 189s. sain No. 666,559. (No man.)

To all whom, t may con/Germ' Beit known that I, JOHN S. DUNN, a citizenof the United States, and a resident of Portage, in the county ofColumbia and State ofV Wisconsin, have invented certain new and usefulImprovements in Railway Signals; and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention has for its object to provide a simple economical signalfor temporary use along railway-lines, the same being especiallydesigned to take the place of the ordinary staff and flag commonlyemployed.

It therefore consists in certain peculiarities of construction andcombination of parts hereinafter set forth with reference to theaccompanying drawings and subsequently claimed.

Figure l of the drawings represents a partlysectional front elevation ofone form of my improved signal and holder for the same positioned alonga railway-line; Fig. 2, a partlybroken side elevation of thesignal-staff shown in the preceding gure, the flag-rod portion.

of the signal being shown in transverse section; Fig. 3, a plan view ofa portion of the signal-holder shown in the rst figure; and Fig. 4, afront elevation illustrating another form of signal in connection withsaid holder, the latter being shown in section.

Referring by letter to the drawings, A represents a portable horizontalarm having one end thereof bent in the form of a hook b for engagementof the inner flange of a trackrail, and superimposed on the arm isajawplate B for engagement with the outer flange of the track-rail. Thearm is shown provided with a longitudinal slot c, and a bolt t Y engagesthis slot and an aperture in the jawplate, a set-nut e being run on thebolt to hold said jaw-plate in adjusted position longitudinally of saidarm. The other end of the arm is provided with a vertical aperture f,the contour of this aperture being preferably angular and oblong, asherein shown. The aperture in the arm is for the engagement of a shankhaving corresponding contour in horizontal section, and this shank may be a metal-point fixture C at the lower end of a wooden sta-ff D, or itmay be a metal rod C', having a signal-target D' fast thereon. As hereinshown, a set-screw g may be employedl housing. Made fast tothe rod isone edge of a signal-flag F,'and the latter being furled on said rodboth maybe swung into said housing out of the way. Y.

A plate G, pivoted at its lower end to staff D, constitutes a closurefor the housing, and a transverse notch h in the upper portion of theplate is for engagement of the aforesaid rod when the latter is swungout to horizontal position, the Hag being then unfurled to serve as asignal. An eart'e'xtends from the notched end of plate G, and when thelatter is in position parallel to staff Dfsaid ear is,

parallel with another ear j, extending from said staff. These ears areprovided with registering apertures, and a hook H, in permanent flexibleconnection with the staff, is engaged with the apertures to hold theplate parallel with said staff. However, other suitable means may beemployed for the same purpose.

From the foregoing it will be vunderstood that when theflag-signal isnot required for use it may be incased in its staff, as shown by dottedlines, Fig. l, so as not to become soiled or torn, and owing to the factthat the flag is suspended from a horizontal rod when in use it cannotbecome wound about said staff.l It also follows that said iiag will begenerally more prominent than those ordinarily employed as a temporarysignal.

In the absenceof the holder, comprising the arm A and adjustablejaw-plate B, the stai D may be set up in the ground along the line of arailway, and the end of its shank is shown pointed to facilitate theplacing of the signal; but a holder attachable to a track-rail isnecessary in conjunction with the all-metal target-signal. (Shown inFig. et.)

By having the aperture in the outer end of the holder and the shank ofthe signal of predetermined oblong contour it is impossible to connectsaid holder and shank without setting said signal so as to display in adirection transversely of the adjacent vrailway-track. It also followsthat the signal is not liable to IOO topple, especially it its shank beoperated upon by a set-screw.

Having thus described lmy invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A portable horizontal arm having one end thereof bent in the form ofa hook engageable with the'inner flange of a track-rail, a jawadjustable on the arm longitudinally thereof to engage the outer flan geof the trackrail, suitable means for securing the jaw in adjustedposition, and a signal having detachable connection with said arm.

2. A'portable horizontal arm having one end thereof bent in the form ofa hook engageable with the innerfiange of a track-rail and its other endprovided with an oblong aperture, a jaw adjustable on the arm'longitudinally thereof to engage the outer ilange ot' the track-rail,suitable means for securing the jaw in adjusted position, and a signalprovided with a shank having detachable match fit in the aforesaidaperture.

3. A horizontal arm having one end in the form of a hook engageable withthe inner fiange of a track-rail and its other end provided with asuitable aperture, a jaw adjustable on the arm longitudinally thereof toengage the outer flange of the track-rail', suitable means for securingthe jaw in adjusted position, a signal provided With a shank havingdetachable match fit in the aforesaid ap-V erture, and a set-screwarranged to maintain the engagement of the sign alshank with saidV arm.

4. A longitudinally-slotted arm having one end in the form of a hook engageable with the inner Hange of a track-rail, a jaw loose on the armfor engagement with the outer flange of the track-rail, a bolt extendingthrough the arn1-slot and an aperture in the jaw, a set-nut run on thebolt, and a signal having detachable connection with said arm.

5. A railway-signal comprising astaft longitudinall y recessed to form ahousing, a rod pivoted at one end within the upper part of the housing,a flag made fast at one edge to the rod, a pivotal closure-plate for thehousing provided With a transverse rod-supporting notch, and suitablemeans for fastening the closure-plate parallel to the statt'.

6. ArailWay-signal comprising a staff longitudinally recessed yto form ahousing, a rod pivoted at one end Within the upper part of the housing,a flag made fast at one edge to the rod, a pivotal closure-plate for thehousing provided with a transverse rod-supporting notch, aperturedmatching ears on said staff and plate, and a hook in' permanent flexibleconnection with the aforesaid staff for engagement with said ears.

7. A railwaysignal comprising a staff longitudinally recessed to form ahousing, a rod pivoted at one end Within the upper part of the housing,a flag made fast at one edge to the rod, a pivotal closure-plate for thehousing, suitable means for fastening the closureplate parallel to saidstam-and a shank on said rod, in combination with a holder organized fortemporary connection with a trackrail and provided with an aperture forthe engagement of the staifshank.

In testimony that I claim the foregoing I have hereunto set my hand, atPortage, in the county of Columbia and State of lVisconsin, in thepresence of two witnesses.
